Cannot load Wireless firmware into STM32WB55 Nucleo board

[zabel]

Hi, am using the STM32WB55 Nucleo board. My problem is, currently I

seem not to have a CPU2 wireless stack loaded and I fail to load file

stm32wb5x_BLE_Stack_full_fw.bin loaded into the Flash. I am using the

STM32CubeProgrammer V2.12.0. When selecting on the Firmware Upgrade

Service Button and clicking on "Read FUS infos", I get:

FUS State: FUS_IDLE

FUS Status: FUS_NO_ERROR

FUS Version: v0.0.0.0

FUS Operator: v3.1.0

When I click on "Start Wireless Stack", this happens:

 13:20:53 : Warning: Option Byte: nSWboot0, value: 0x0, was not modified.

So it seems, there is no Wireless Stack present. And if I try to load

it, this also fails: I want to use stm32wb5x_BLE_Stack_full_fw.bin

(V1.15). From the release note, I learn that the correct start address

is 0x080CE000. I have the

"First install" checkbox deselected, and the "Verify download"

selected. The Start Address field is set to 0x080CE000. On clicking

"Firmware Upgrade", I get this log:

And when trying to start the firmware, I still get 2 dialog boxes

I have found some similar questions:

• Issue: Attempting to flash firmware onto coprocessor on STM32WB55RGV6

results in Error: FUS_STATE_ERR_UNKNOWN

• [STM32WB55 Nucleo] Unable to update FUS or the wireless stack

(FUS_STATE_ERR_UNKNOWN)

but both threads do not seem to have a solution.

I also read the AN5185 as well as the STM32WB_FUS wiki I am not allowed to post a link here, so I will split it:

"stm32mcu/wiki/Connectivity:STM32WB_FUS"

on

wiki.st.com/

but to no avail.

I tried to identify the FUS version. IPCCDBA option byte is 0, but the whole

memory starting at 02x0030000 contains only 0x000000, so I don't find

the Device info table.

The SBRV option bytes contain 0x3d800, so this seems to indicate I

have FUS V0.5.3 loaded.

These seem to be the relevant option bytes on my board:

RDP: 0xAA (nor read protection)

nBOOT0: 1

nBOOT1: 1

ESE: unchecked

SFSA: 0xd4

FSD, DDS, C2OPT, NBRSD: checked

SNBRSA: 0x13

BRSD: checked

SBRSA: 0x0a

SBRV: 0x3d800

Any help would by nice!

Still no success, latest try was reducing the stlink speed to 100kHz.

Same here

Refer this wiki for such issues: STM32WB Firmware Upgrade Service - stm32mcu (stmicroelectronics.cn)

See section FAQ.

Most of the time, safeboot is triggered due to corruption in option bytes or voltage fluctuations. See specifically 

Accidentally, I got SFSA = 0x00 and SBRV= 0x3FC00 what's happened?

This is due to option byte corruption, or to supply voltage or level stability. This configuration of the SFSA/SBRV option bytes means that the STM32WB hardware forces the boot to Safeboot whatever the firmware being run. To activate Safeboot and perform a factory reset the user must activate the Cortex-M0+ by writing the value 0x00008000 to address 0x5800040C using the SWD interface. If a FUS version lower than V1.1.0 is running, then no recovery is possible at this point.
